I have a problem that for some reason my $_SESSION variables seem to be empty when I am trying to echo them onto the form you can see on the picture. The name field (‘Név’ on the picture) works, however it is from another table from my database.
Here are the corresponding PHP code snippets:
personal.inc.php:
<?php
session_start();
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
require_once 'dbh.inc.php';
require_once 'getpersonal.inc.php';
if (isset($_POST["submit_personal"])) {
$birthdate = $_POST["birthdate"];
$bio = $_POST["bio"];
$dailyTime = $_POST["chintime"];
$favChin = $_POST["favchin"];
$ownsChinchilla = $_POST["owns_chinchilla"];
$loveTime = $_POST["year_selector"];
$userID = $_SESSION["id"];
$new_name = $_POST["name"];
$nameUp = "UPDATE user_form SET name='$new_name' WHERE id='$userID'";
$conn->query($nameUp);
$checker = "SELECT COUNT(*) FROM personal WHERE userID = '$userID'";
$result = mysqli_query($conn, $checker);
$row = mysqli_fetch_array($result);
if ($row[0] > 0) {
$stmt = $conn->prepare("UPDATE personal SET bio = ?, birthDate = ?, dailyTime = ?, loveTime = ?, favChin = ?, owner = ? WHERE userID = ?");
$stmt->bind_param("ssssssi", $bio, $birthdate, $dailyTime, $loveTime, $favChin, $ownsChinchilla, $userID);
} else {
$stmt = $conn->prepare("INSERT INTO personal (userID, bio, birthDate, dailyTime, loveTime, favChin, owner) VALUES (?, ?, ?, ?, ?, ?, ?)");
$stmt->bind_param("issssss", $userID, $bio, $birthdate, $dailyTime, $loveTime, $favChin, $ownsChinchilla);
}
getPersonal($conn);
$stmt->execute();
$stmt->close();
$conn->close();
}
header("location: user.php");
exit();
?>
getpersonal.inc.php:
<?php
require_once 'dbh.inc.php';
function dataExists($conn, $userID) {
$sql = "SELECT * FROM personal WHERE userID = ?;";
$stmt = mysqli_stmt_init($conn);
if (!mysqli_stmt_prepare($stmt, $sql)) {
header("location: login.php?error=stmtfailed");
exit();
}
mysqli_stmt_bind_param($stmt, "s", $userID);
mysqli_stmt_execute($stmt);
$resultData = mysqli_stmt_get_result($stmt);
if ($row = mysqli_fetch_assoc($resultData)) {
return $row;
} else {
$result = false;
}
mysqli_stmt_close($stmt);
return $result;
}
function getPersonal($conn) {
$dataExists = dataExists($conn, $_SESSION["id"]);
$_SESSION["bio"] = $dataExists["bio"];
$_SESSION["favChin"] = $dataExists["favChin"];
$_SESSION["owner"] = $dataExists["owner"];
$_SESSION["birthDate"] = $dataExists["birthDate"];
$_SESSION["dailyTime"] = $dataExists["dailyTime"];
$_SESSION["loveTime"] = $dataExists["loveTime"];
}
?>

I would like to echo the $_SESSION variables into my form when they are set in my database, so if the user only updates 1 field, the other fields won’t be touched.
Any form of help is appreciated,
Blaise
